Operation and Maintentance Cost Estimator (OMCE) - Final Report

This report is written in the context of the project Operation and Maintenance Cost Estimator߿ݬ which is carried out within research line 5 (RL5) of the Dutch research program We@Sea. The aim of this project is to develop a methodology for owners and operators of offshore wind farms to better estimate and control the future OaM costs taking into account operational experience. In addition to We@Sea, who has partly financed this work also Nordex AG is thanked for supplying the required information of the Nordex N80 wind turbines. The project made use of the Nordex N80 wind turbines located at the ECN Wind turbine Test site Wieringermeer (EWTW). EWTW supplied maintenance sheets, SCADA data, and PLC data to the project team for further processing and enabled various measurement campaigns. Finally, the authors want to thank Noordzeewind and SenterNovem for providing OaM and logistics data of the Offshore Wind farm Egmond aan Zee. This project was funded partly by We@Sea and partly by ECN (EZS).
